I use opposite directions on my trackpad and my scrollwheel, take that! Ha!

Trackpad I’m grabbing with my fingers so I want the surface to move in the same direction as my fingers.

Scrollwheel I feel like is a roller that sits on top of the surface so I have to roll down to make the surface move up.

Unfortunately, at least in macos, you need 3rd party software to achieve this

My partner has his stuff set up exactly opposite from you!
